T0 all whom t may concern:

Be it known that I, WILLIM Jol-1N DEM- MING, a citizen of the United States of America, residing at Hurley, in the county of Surrey, England, have invented certain new and useful Improvements in and Relating to Machines for the Manufacture of Glass Bottles and the Like, of which the following is a specification.

This invention relates to glassbottle-blow in machines, and is more especially applica le to machines for the manufacture of narrow-necked bottles.

The invention'has also for its objects to more eiiectually form the mouths ofthe necks of the bottles so that there may be ne waste due to improperly-formed necks, as is the case in existing machines for the manuacf ture of narrow-necked bottles; to provi `e means for projecting the moutlli-fornung nipple into the parison and withdrawing it at any time as may berequ'ired accordiig to the nality of lass and other condtions which t e skill org the operator will degerminegto provide means for the ready renewal Vef/th'e mouth-forming nipple, and to provide means for the interchange of nipples of various form, and size as required accz'ordingr to the kind of bottle to be produced. f

The invention, moreoverpcffzitempiates an improvement in the actual operation of plunging the parison and blowing the bottle, and also involves constructional features which are hereinafter more particularly described.

In carrying the invention into eilec't in its applicationto a machine for the manufacture of narrow-neck bottles I provide a rotating bracket upon which the neck and pari-- son molds are hinged in such manne Vthat the parisomrnold is capable of being inver ed for the charging operation and is capable of assnrnin a diametrically opposite position for the b owing and finishing to be performed. The mounting of the neck and pausen mold in such manner and for such known in machines of this class. Within the hess of the rotating bracket aforesaid l provide the plunger, which I advantageously mount within a sleeve, which latter is ea able olea slight vertical displacement. 'ilul sleeve aforesaid is conveniently provided al its lower extremity with a boss having n purpose is we flange or rim at its lower extremity provided to engage Within a correspondingly' shaped recess within the neck -mold )arts in the manner hereinafter more particularly de scribed. The Said boss is bored out to receive a bush provided on its inner eriphery with screw-threads, advantageous y square threads. This bush is fixedly connected to the boss aforesaid by means of a Vscrewed pin or by any other suitable means. Within the bush an internal nut is provided, having threads n pen its outer periphery corresponding to and engaging with the screwthreads on the inner periphery of the bush.' It will be understood that the )lun' er passes through the internal nut. iep unger is provided with an axial keyway'throughout part of its no matter what the position ol' the plunger the 'pliinger on its rotation shall be capable of causing the rotation of the internal not for 'che urpose that will i'nnncdiately appear. The Internal nutis provided with an annular x'recess surrounding the plunger for the reception of the shank of the mouth-forming nipple. .The shank is secured tothe internal nut by means of a small screw, which is irovided with a tcat at its extremity which when the screw is turned home engages in a corresponding hole within the shank ol' the lnoutlvforming nipple, and thus eflectually retains the nipple 1n position. By so roviding the mouth-forming nipple it wil he understood that there is no necessity of roviding a screw-thread upon it or of mae iining it in any way, and the mouth-formingr` nipple may thus he ro'vided of the hardest metal to withstand t ic great heat to which it is suh'er-.ted iu use. The hush aforesaid is provided with a hole sullieiently large for the imssage through it ol' the 'screw aforesaid when it is required to renew or replace the mouth-forming nipple. According` to the invention a molding-rin;r is provided independent of the mouth-forming: nipple lor the formation of the edge of the mouth, und this molding-ring is provided with a llange, by means oi which it may he connected to the lower end ol' the hush aforesaid by means ol a uut. liv such a construction it will ho understood that the nip lc and the plunger may he plunged or wltlulruwn quite inde pendently and at the proper moment and lor length, the keywayleing of such a length that a determined time, asI may be re uired, ac cordinf.;r to the particular ualityo the glass that is ein loyed and ot er conditions of working. so providing the plunger and the mouth-forming,r nipple with this capability of independent movement I contemplate accordingr to the invention to form the neck by charging the mold with metal with the plunger complctel withdrawn and the mouth-forming nipple almost completely withdrawn. 1 ani then able to first project the mouthforming nipple into the parson, and this movement can then be immediately followed by the movement of the plunger. The mouth-forming nipple may then be iminediately withdrawn and the plunging and blowin operations ma be partiallyor wholly effecte with the nipple in its retracted position. By such means a great advantage results by reason of the mouth-forming nipple being in the casting osition for the minimum time and the li e of the nipple is thus substantiaily prolonged.

In the provision of a screw-nipple for forming a screwing-mouth I ma provide the molding-ring with a conical rim, and I may provide the rin with an internal screw exactly correspon ing with the screw upon the screw-nipple, so that the screw-nipple may be passed to and fro within it.

I may effect the rotation of the plunger for retractin the internal nut and the nipple by means o a pinion sliding in a keywesy provided on the plunger, the pinion being moun ed at the top of the plunger-boss and bein advent: geously provided with a flange wliic is grooved or recessed, so that a fixed fork plate may be introduced within the annular groove or recess thus formed for maintaining the pinion in a fixed position i/vith reference to tie plunger, while permitting of its rotation by means of a toothed wheel or toothed seszment operated'by means of a handleor ot ierwise, as may be convenient.

It will be understood that I prcferaby provide the boss carrying the hush, internal mit, and nipple tofhave a slight vertical displace-- ment, so that on the opening of the neck-inolds means may operate*such as a springY or springs, leveror levers oi' other simple nicchanisin for bringing tlie molding-rmar out of the mouth ofthe bottle on opening the neckmold. 'lhi's movement, it will be understood, is of small extent.

The plunger ma f hc provided of a number of parte as may ic required for construc' tional purposes, and it may bc provided with a bore and transverse arts, which may be provided to correspond with ports or uissages in the sleeve or in thc carrying-brac et, so that the blowing o )eration may bc ii-rger or otherwise in the manner well known in machines ol' this class.

The invention is illustrated iii the accompanying drawings, in which-- Figure l represents a sectional elevation of thc pluiigcrcarrying bracket. and neck-molds of a glass-hotile-blowing machine to which` the invcntion is applied. i Fig. 2 isasectional elevation of a modilii'ation In Fig. l the invention is shown applied witha screw-inout h nipple, while in Fig. .2 it is shown applied with a corking-mouth nipple.

per part of the nipple 2l, so that thus there' may be no necessity for providing the holes` in the shank ofthe nipples with screws. The upper part of the sleeve .20 is provided with a long pinion 23, which gears with a toothed segment by which it is rotated as required in the operation of the machine.

Integral with the inion 23 and sleeve 2() is a screw-nut 24, whic works within the upper screwed part 25 of the sleeve r in such manncr that upon the rotation of the inion 23 by means of thc toothed sc ment i f the vsleeve 2() is moved u wardly or ownwardly, accordingr to the ircction of movement of the toothed segment W, so as thus to lift uprand rotate the screwed nipple .21 out. of the neckniold or to rotate it into the ncck-mold, as required.

U on the lower extremity of the sleeve r a. mol in i'-rin 26 is provided b which the edge o the ottle is cast, and tiis moldingring is maintained in position by means of a screw-nut '271, which rests upon the top of the neck-mold parts.

The neck-mold parts e are recessed and provided with an annular recess in which segments 27 are provided with inclined faces, which on thc closure of thc mold engage with corresponding inclined faces formed .upon the cxtrcniit of thi` slccve r, so that thc latter ma)v bc rouvht down in close contact with the neck-molding ring e". 'Ihe segments arc mounted in position by moans of pins 28, and thc position of thc inclined edge of the segments 37 is dcteri'oined b such means as grulescrcws 29, as illustrate( .i
